Tire Size Measurement – Basic Concepts

The tire size measurement is a way to identify the particular type of tire in terms of its width, height, diameter and other components. The size is usually expressed in metric units, such as millimeters (mm), centimeters (cm) or inches (in). It is used to indicate the size of the wheel and tire combination that should be used in a vehicle. The actual measurement of the tires will vary depending on the manufacturer and type of vehicle.

Tire sizes are expressed in two ways: one is a numerical expression that includes the aspect ratio, width, rim diameter and type of construction; and a second is an alphabetical expression that includes the load index and speed rating.

When it comes to measuring tires, there are several methods available. These include using calipers or micrometers for measuring external diameters, as well as tread depth gauges for measuring tread depth. The measurements taken with these tools can then be compared to manufacturer specifications to ensure accuracy.

285 70R17 – Variables and Specifications

The 285 70R17 tire size means that the tire has a section width of 285 millimeters (mm) or 11 3/16 inches wide from sidewall to sidewall, with an aspect ratio of 70%. This means that the height of this tire from its base up to its tread is 70% of its width. Additionally, this type of tire has a 17-inch rim diameter which means it fits on a 17-inch wheel rim. It also has an R designation which stands for radial construction technology meaning that its internal structure consists of multiple layers running radially across the circumference instead of circumferentially around it like with bias ply tires.

This type of tire offers many benefits including improved fuel efficiency due to reduced rolling resistance and improved handling due to better traction capabilities when cornering at high speeds. Additionally, radial construction also provides increased durability since radial tires can withstand higher loads without deformation compared to bias ply tires.

33×12 50R17 – Variables and Specifications

The 33×12 50R17 tire size means that this type of tire has a section width of 33 inches (838 mm) wide from sidewall to sidewall with an aspect ratio 50%.
